Need help identifying this wild plant in my yard

[Kokoliko]

Hi All,

Recently, we've been getting alot of these wild, fast growing plants in our front yard.

They're green, with big leaves with a green stalk. They can grow from less than 1 foot to 4 feet in a matter of weeks. In fact, I noticed this one particular plant grow from 4 ft to 6 ft in less than 2 weeks.

I try to pull them out when they're small and easy to pull out. We recently completed a major landscaping project and I'm in the process of laying out new sprinkler system and eventually grass. So our front yard hasn't had any water the last couple of months. Despite the lack of water, these plants are growing all over and growing fast.

Can someone please take a look at the attached pictures in hopes you can identify them for me please?

Thank you in advance,

Koko

I recently had a friend ask me over to id a beautiful bush that had suddenly sprouted from from top dressing she had used in her flower beds and it turned out to be a very healthy bush of mariwana or dagga as we call it here . She had been watering this bush with runoff water from her orchids. When I told her what it was she chopped it up and wanted to burn it ,but when I told her that that would most probably send the folks next door on a trip ,she decided to just put in the garbage!!
